An exhaust valve is arranged on the pot cover, and an automatic exhaust device is arranged on the pot body. The automatic exhaust device is used to lift the exhaust valve upward to realize exhaust and pressure reduction of the pot body during cooking or after cooking.

[0024] Combination Figures 1-6 As shown, the automatic exhaust device is installed on the inner wall of the shell 1 of the pot body, and is used to lift the exhaust valve of the pot cover upward as needed to operate the exhaust valve to realize automatic exhaust.

[0025] The automatic exhaust device specifically includes: an electromagnetic valve 2 fixed on the inner wall of the shell 1 of the pot body, the valve rod 21 of the electromagnetic valve 2 has a stroke D1; a lifting rod 3 arranged between the electromagnetic valve 2 and the exhaust valve; and a stroke amplification mechanism arranged between the end of the valve rod 21 of the electromagnetic valve 2 and the lower end of the lifting rod 3.
